Description: The 2ply wrap tapes mainly consists of polyethylene film backing
and the adhesive layer whose main component is butyl rubber. It is
produced through extruding the composite anticorrosion materials.
The adhesive layer is attached to the polyethylene film backing
through thermal compounding. The anticorrosion system is comprised
of primer, anticorrosion adhesive tape (inner tape) and protective
tape (outer tape) or only primer and anticorrosion adhesive tape.

Other name :

2 ply wrap tapes also called pipe anticorrosion adhesive tape, pipe
anticorrosion tape, polyethylene cold wrapping tape, composite
polyethylene anticorrosion adhesive tape, etc. Featuring excellent
insulativity, good anticorrosion effect, high mechanical strength,
small water absorption, long service lifetime, good resistance to
impact and ageing, the product can be used in the construction
conveniently with safety and no pollution. It is widely applied in
many areas with high efficiency.

Usage:

mainly used for outer surface anti corrosion of the steel pipeline
which is buried under the ground for petroleum transportation. It
has been used as the external anticorrosion material for oil and
gas steel pipeline for more than 40 years since 1960s. The merits
of excellent property and convenient construction allow the product
to play a very important role in the pipeline anticorrosion
material system. With the continuous improvement in specification
and quality of the product, the application range of the product is
expanded largely and constantly.

Prepare surfaces by removing all loose scale, rust or other foreign
matter by grit blasting or wire brush. Surface must be clean, dry
and free of grease.Apply thin film of Butyl Primer to all surfaces
to be wrapped and allow to dry. Peel back interleaving and apply
adhesive side of the tape to the surface and press down. Apply the
tape spirally with enough tension to make it conform. Remove
interleaving as wrapping proceeds. Overlap each turn by at least 1"
or 55% to achieve double thickness.

Irregular surfaces such as valves, flanges, etc. may require the
use of Mastic or Profiling Mastic.( we can supply it also ) Refer
to the product sheets for these specific

-Provides corrosion protection with the inherent chemistry of
Polyethylene and Butyl Adhesive for resistance to water and oxygen
penetration. Oxygen and Water are prevented from reaching the metal
substrate, which are necessary and sufficient conditions for
corrosion.
